The Lagrangian is: L = mR2 2 2 sin2 +2 It used to be considered the sum total of our theoretical knowledge of the physical universe (Laplace's daemon, the Newtonian clockwork), but now it is known as an idealization, a toy model if you will. This yields the correct Lorentz force lawmx = q(E+vB) for the parti- Generalised classical mechanics has developed considerably since the time of Lagrange special relativity. Chapter 1 From Newtonian to Lagrangian Mechanics Classical mechanics is a peculiar branch of physics with a long history.

From order to chaos In each chapter, the reader will nd: The Lagrangian formulation 2. The advantages of lagrangian mechanics comes in handy in this situation since using the cartesian coordinate system requires a lot of work. It is valid for relativistic particles even though it was developed by Leonhard Euler and Joseph-Louis Lagrange in the 1750's. L L(q,q) (22.21)

Because this is new and strange, I'll stress once again that this is a reformulation of classical mechanics as you've been learning it last semester; it's just a different way of obtaining the same physics .

An Introduction to Lagrangian Mechanics begins with a proper historical perspective on the Lagrangian method by presenting Fermat's Principle of Least Time (as an introduction to the Calculus of Variations) as well as the principles of Maupertuis, Jacobi, and d'Alembert that preceded Hamilton's formulation of the Principle of Least Action, from which the Euler-Lagrange equations of motion . The symbol q is a generalized coordinate used to represent an arbitrary coordi-nate x,,, etc. as well as to relativistic and quantum mechanics, are included. 2.
